This thesis focuses on the development of a data-driven decision support system to assist the Egyptian procurement activities in foreign countries. The Egyptian Procurement Office in Washington D.C. (POW) is taken as a example to apply this research. Two areas of procurement type have been examined in POW, The Commercial Procurement and the Foreign MIlitary Sales (FMS) system. The Data Flow Diagram technique has been used to analyze the system. PC/FOCUS has been used to design a prototype software for the POW Commercial Procurement subsystem to use in an IBM-XT, IBM-AT, or compatible microcomputers.
